If you want to use numbers to calculate, it is generally about 200 times in the case of high power. Small dumbbells can hardly increase muscles. Beginners must understand the principle of muscle growth. For some fitness enthusiasts with weak constitution, it is necessary to clarify the principle of muscle growth so as to use it in future fitness and avoid improper methods and putting the cart before the horse affecting the fitness effect.

Simply put, muscle growth is a process of stimulation, supplement and growth. As we all know, the growth of muscle requires strength training, that is, high-load and high-intensity training to stimulate muscle, so as to achieve such a process of muscle fiber destruction, and then the body mobilizes nutrients through its own immune function to repair. At this time, bodybuilders need to supplement nutrition, provide materials needed to repair muscles, and promote the body to complete the process of recovery and excessive recovery, so as to achieve the purpose of muscle growth.

Therefore, for bodybuilders who aim at muscle growth, the main task is to increase the training intensity by increasing the training weight and the number of groups, to realize deep muscle stimulation, so as to realize the process of muscle fiber destruction, and then to help the body complete the process of excessive recovery through nutritional supplement.
